Scorpion and Ash are amazing.
But even if its 1v1 I would like to see Ash with open top. Its always annoyed me in this map that its claustrophobic as hell, not only because of two small buildings but because that really low ceiling. I remember that I had somewhere Ash map at night with open top, it was not perfect but playing a bit with jet amount and construction of walls this would be really nice change from all those closed maps.
